Specification of Letters Patent.

Application med November 16, 1920. Serial No. 424,525.

To all whom it may concern:

Be it known that I, HARRY H. HiPwnLL, a

citizen of the United States, residing at Pittsbur h, in'the county of Allegheny and State of ennsylvania have invented a new and useful Fl'ashlight-iBattery, of which the following is a specification.

By way of explanation, it maybe statedflash that in the manufacture of cells for light batteries, a core is provided, the core being made of manganese, graphite and other chemicals, the core being wrapped in a cover, often made of muslin. After; the cover is in place about the core, the geommon practice, heretofore, has been to tie the cover in place with a piece of thread. The operation which consists in tying the cover in place with a thread, is disadvantageous for a number of reasons. First, the tying with a thread is a slow and tedious process, and it is exceedingly difficult to find operators who can work up suflicient speed, or to train operators to such a speed that the tying operation need not be considered seriously as one of the overhead items in the manufacture of flash light battery cells. Again, -in some instances, it is necessary to provide an insulation for the core, and, obviously, a thread does not form an. adequate insulation.

The foregoing considerations being understood, this invention aims to provide novel means, in the form of a rubber band, whereby the cover may be held on the core of a flash light battery, and, at the same time, efficient insulation may be afforded.

It is the object of the invention, further, to provide means whereby time may be saved in the securing of a cover on a battery core, the cost of manufacture being decreased accordingly.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the place,

precise embodiment of the invention shown can fbe made without departing from the spud; of the invention.

In the accompanying drawings 2- Flgure 1 shows in side elevation, a flash llght battery core whereon the cover is held by. the device forming the subject matter of this application, parts being broken away;

Fig. 2 is a plan showing one/ end of the-core;

Fig. 3 is a plan showing the opposite end of the core; andFig. 4 is a diagrammatic perspective showing the rubber band as it may appear when mounted on the core.

The. numeral 1 marks the core of a flash light battery, the corehaving a stem 2. A cover 3, sometimes made of muslin, is wrapped transversely around the core 1, the

longitudinal edges of the cover being over-.

lapped on each other, as shown at 4. The cover 3 is folded at one end as shown at 5 on the corresponding end of the core 1, about the stem 2, the opposite/ end of the cover being folded, as indicated at 6, on the corres onding end of the core.

11 order to hold the'cover 3 on the core 1 and to provide adequate insulation, one or k more rubber bands are employed, the bands being applied in various ways. Preferably,- however, the band is fashioned intoanydesired number of convolutions 7 surrounding the stem 2 closely, at one end of the core 1.

The band is extended, from the convolutions 7, to form a loop, portions of which, indicated at 8, extend transversely of one end of the core 1, adjacent to the stem 2. The sides 9 of the loop extend longitudinally of the core, the bight 10 of the loop extending across the base of the core. One side portion of the loop is crossed on.itself, as shown at 11 and is fashioned into any desired number of convolutions12 which are snapped around the core.

The construction is such that the folded ends-5 and 6 of the cover 3 will be held in and, at the same time, the longitudinal edges of the cover will be held in overlapped relation as shown at 4.

One or more rubber bands may be applied as above described, to a battery core, with great rapidity,'the costof manufacture'being decreased. Further, it should be recalled that, when the device forming the subject matter of this application is resorted to, an adequate insulation is afforded by the rubber band.

Having thus described the invention, What is claimed is In a device of the class described, a flash light batterycore including a stem; a cover surrounding the core; a rubber band formed into a plurality of convolutions surrounding the stem, the said convolutions being extended to fashion a loop disposed longitudinally of the core, one side portion of the loop being crossed on itself and being formed into convolutions surrounding the core transversely.

In testimony that I claim the foregoing as my oWn, I have hereto afi'ixed my signature in the presence of two Witnesses.
